SiGe Semiconductor to Deliver a Series of WiMAX RF Front-End Modules

(Product News, 28 Sep 2007)

SiGe Semiconductor plans to deliver a series of radio frequency (RF) front-end modules for WiMAX systems—which will combine the company's high-performance WiMAX power amplifier architecture with the its expertise in multi-chip module integration.

The series is scheduled to begin rolling out in early 2008 with sampling of the SE7261, a front-end module designed specifically to support the requirements of laptop computers. SiGe Semiconductor's roadmap also includes chip-scale front-end modules for small handheld devices including personal digital assistants and cellular handsets, as well as higher output power modules for customer premises equipment.

Each of SiGe Semiconductor's WiMAX front-end modules will incorporate all of the circuitry required between the transceiver and antenna, including the power amplifier, power detectors, filters, switches, matching and bias components. Based on SiGe Semiconductor's high-performance power amplifier, the front-end module delivers over 20% efficiency at 24dBm output power.

SiGe Semiconductor's new front-end modules will be compliant to the IEEE 802.16e specification, commonly known as mobile WiMAX.
